Abstract

Synthesis of biolubricant through chemically modified suberic acid (SA) with 3 different types of alcohols which are 1-octanol (Oc), 1-decanol (De) and 1-dodecanol (Do) was conducted with presence of 4% p-toluenesulfonic acid (PTSA) as a catalyst. Preparation, characterization and physico-chemical properties of three types diester (suberate) is discussed in this paper. The diester products were confirmed by NMR and FTIR spectroscopic analysis. Addition of alcohols at the side chains of diacid increases the molecular weight and chain length resulted in the increment of viscosity index (VI), oxidative stability (OT) and flash point (FP) of the diesters. The result showed that 1,8-dioctanyl suberate (DOS) exhibited the most favorable low temperature performance (PP -8.5°C) while 1,8-didodecanyl suberate (DDoS) exhibited higher OT (190°C) and higher FP (224°C) than the other diester oils. On the other hand, the highest VI around 197°C was obtained for 1,8-didecanyl suberate (DDS). These diester oils have a good potential in formulation of industrial biolubricants.
